after seconds lcd display started to getting crazy.it started to show meaningless characters,numbers or smiles

I have seen this as well. Some times applying a little gentle pressure on the face of the charger just around the edge of the LCD fixes the display problem. This suggests the problem is not firmware going crazy but simply a poor contact somewhere.

In terms of its specifications the charger would have no problem charging a 2S pack at 6A. IMO the problems I experienced were not specifically related to the charging rates I was using but to design, build or QA issues.

Hi Kgfly,
I am looking at getting one of these. I will be using it soley to charge 6s 5000 lipos. I am hoping to charge at about 7.5A per side (15A in total). Have you any update on how you think this charger will cope with this task? They are fairly decent lipo packs (nano-tech).
Cheers, Paul.

To charge a 6S lipo at 7.5A requires about 180W charger output power. From a specification point of view this charger should be able to deliver that on both ports so long as you have a suitable power supply (at least 15V/30A, 450W).

As you know from this review, my experience with this charger was not good. Hence in your situation my choice would be a more powerful/accurate single-port charger (eg FMA PL8 or iCharger 306B or 3010B) and charge them in parallel at 15A-20A. If you want the flexibility of two ports then get two 6S,10A/200W chargers with better features, UI and accuracy (eg iCharger 106B+, 206B or 208B or Hyp 720i) or if you really want a DUO-style the get the Hyperion 0615iDUO3.

I am going to stop looking now - otherwise I will never take the plunge.
Still winter is here now..... Very cold, wet, rainy, windy, dark, miserable. Still its only like that until march - by then hopefully I will have eveyting in place and a big new trex 600 flybarless with big batteries (beautifly charged on my new charger).

That PS will do the job for the 615iDUO3 but the voltage is too low for most 300+W chargers which typically need in the 18-24 range. I mention it only so you won't buy it thinking "this will do me for now and be good for whatever I need in the future". For example you could not run the Fusion L720B DUO charger (2 x 7S,20A/300W) full bore using that Fusion PS.

If you are not in a great hurry I would wait a few months. The charger and PS market is moving very fast. There is a new Hyperion DUO out soon, the 720iSDUO3 (2 x 7S,20A/500W) which needs a 24V/55+A supply to deliver its full oomph. There is a rumour of a new Junsi/iCharger DUO-style unit as well.

There are some 30V/30+A 900+W supplies out there if you look around. Some are raw SMPS that you have to wire up and others are proper bench supplies in cases, with displays and terminals.

Demand from the RC world for 18-24V/1000+W PS is very new but growing quickly. I think we will see more supplies appearing in the next six months.

Finally, there are some good threads here on RCG on how to use low-cost server PS if you are electrically handy.

Just bought one of these myself, and it arrived a few days ago. Haven't had a chance to use it yet, just studying how to use it and checking it over.

So in this cheking over I noticed something that looked odd, and then I saw why. It's the face plate on the panel with the connection jacks and ports.
It's put on upside down, which prevents plugging in to the USB power output and the balance ports. I don't know whether to call Hobby Lobby and see about a replacement, or just try to remove it and glue it back on. Im sure thats possible but I know there's a strong chance of bending it up in the attempt to remove it. So I think I'll give them a call and see what they say.

Ok so Hobby Lobby replaced the unit for me(thanks Beth in HL support)
I just now have recieved the replacement, and this time the faceplate is correctly right side up.
So now to get down to the business of learning to use it. This is my first charger of the type, and must admit it'll take to thorough study of the manual to grasp it's many features. I've only used a polycharge4 up to now, and before that just a simple Eflite Celectra before that(no displays on either one)
To me the manual seems somewhat vauge and un-detailed. Im one who likes to know the why of things, and lots of detail so it seems lacking in that. Plus the usual poor choice of words is present in some places. So this will take some reading between the lines. Adn I probably ought to have somone familiar with Imax chargers walk me through the first few uses.

Anyway, glad to finally have it in my hands and also I have the eFuel 20a PS also from HL. Yes I know it'd be better to have the 30a one but HL didn't have but this one availible. But the largest battery I have to charge is a 3S 3000mah so I should be fine.
